Great work! I'm about to decide which solution I'm gonna use for making mind maps while studying and I like this one alot.. Any chance there'll be google drive connection in the near future?
Edit: I seem to have a problem with scrolling in the document. When I try to scroll using two finger swipe on a mac it sometimes recognise the scroll as a zoom in/zoom out command instead, until I reload the page and I can scroll normally again. Is there any other way to scroll? Am I doing it wrong? (and sometimes the the browser recognise the two finger swipe as a back command..)
